The electrical efficiency is defined as the ratio between the useful power output and the total power input:

In our problem,

(power generated by the solar panel) and

(power hitting the surface of the solar panel), therefore the efficiency of the panel is

which corresponds to 30%.
Answer:
a) dB / dA = 2
,
b) Network B Network A

Explanation:
a) The expression for grating diffraction is
d sin θ = m λ
where d the distance between two slits, λ the wavelength and m an integer that represents the diffraction range
In this exercise we are told that the two spectra are in the same position, let's write the expression for each network
Network A
m = 1
sin θ = 1 λ / dA
Network B
m = 2
sin θ = 2 λ / dB
they ask us for the relationship between the distances, we match the equations
λ / dA) = 2 λ / dB
dB / dA = 2
b) let's write the equation of the networks
sin θ = m_A λ / dA
sin θ = m_B λ / dB
we equalize
m_A λ/ dA = m_B λ / dB
we use that
dB / dA = 2
m_A 2 = m_B
therefore the overlapping orders are
Network B Network A

True because you cannot see the wind
Answer:
A. continental-oceanic convergent
Explanation:
I knew it couldn't be B because it's oceanic and <em>continental</em>, not oceanic and <em>oceanic</em>.
Next, I noticed the word <em>convergent</em>, which implies "coming together" to me.
I looked it up and noticed the term <em>convergent</em> referred to a plate boundary where a plate slips under (<em>subducted</em>) another, so I knew it was A.
Hopefully, this helps you understand the question better. Have a great day!
I electromagnets, the magnetic field is turned off when there is no induced current. So, electromagnets act as magnets only when current is induced in an insulated wire wrapped around a material mage of ferromagnetic material such as iron core rotating in a magnetic field.
So, option D is the correct one.
